ATTACHING MACHINE.

Application filed July 23,

T 0 all whom it may concern:

Be it known that'l, Josnrn H. Porn, a citizen of the United States,residing at Hamilton, in the county of Essex and State of Massachusetts,have invented certain Improvements in Attaching Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to attaching machines, as those in which nails,tacks or other fasteners are driven to secure various elements. It isespecially applicable to shoe machines, being here illustrated inconnection with apparatus for attaching counters. Such apparatufurnishes an instance of the need for driving fasteners in varyingpositions, determined by conditions surrounding the parts associated,but not necessarily directly connected, with the part to be attached. Inapplying molded counters to turn shoes in accordance with the method ofPatent 7 No. 1,868,373, Toothaker, Feb. 15, 1921, a counter with a tuckor shank-piece stapled thereto is secured t the sole by nails,customarily four in number, driven in the area between the center ofthe'heelseat and the breast-line. To permit proper attachment when awood heel is to be applied to the shoe and nailed from the inside, as isusual, the heel-attaching nails must, of course, clear the previouslydriven counter-attaching nails, and these heel-attaching nails vary inposition for different sizes and types of heels. Moreover, as the formof heel changes, the position of the heel-breast longitudinally of theshoe also changes, so that a nailing design for the counter which fellwith-in the heel-seat area for one form might be outside for another,causing the counter-attaching nails to pass through the shankportion ofthe sole. It is consequently important that such machines as those forattaching counters should include means for alteringv the nailing designto correspond to the conditions existing in the particular shoe operatedupon. In accordance with a practice which has heretofore obtained, thedie-block and counter-holdingv block of the counte'rattaching machine,and also the loader-block which is to dc liver to the die-block, hasbeen provided the foot-plate 1921. Serial No. 4810M,

with a plurality of sets of nail-receiving openings, so situated thatsome, one of them 'distributor of the machine has been furnished with acorresponding number of re movable foot-plates for the tube-holder, eachplate provided with delivery-openings, in which the tubes may beinserted, equal in number and corresponding in arrangement to one of thesets of receiving-openings of the loader-block. Such an organization,involving the interchange of plates and the complete transfer of thetubes from the openings of one plate to those of another for eachnailing design employed, proves so burdensome to the operators that theyneglect it, and upon a change in the style of the shoe will continue theuse of the design for attaching the counter of the previouslyoperated-upon shoe, which may cause the difficulties indicated above. Itis an object of my invention to provide an attaching machine havingmeans for changing the nailing design, which means is simple inconstruction, and is so readily operated that its use will seldom beneglected.

A particular embodiment of my invention is illustrated-in theaccompanying drawing,

Figure 1 being a broken perspective view of portions of acounter-attaching machine including said invention;

Fig. 2, a vertical, sectional detail through of the distributingapparatus and the associated loader-block;

Fig. 4:, a broken side elevation of the heelportion of a shoe,illustrating the relation between the counter-attaching andheel-attaching nails for heels of different forms.

Generally, the machine shown resembles in its wo-rk-supportin,pressure-applyin and nail-driving mec anisms, the well? known Lightningheel-attaching machine, which need not here be described. The die-block10 and one of the side-rods 12 of this apparatus appear in Fig 1-. Uponthe under side of the die-block is mounted the most essentialdistinguishing element of the counter-attaching machine, which con- 7this foot-plate is shown an tangular in form, to receive a plate-sectionsists of a counter-holding block 14, having nail-receiving openings 16alined with the corresponding openings of the die-block. This block 14is so formed and arranged as to receive and hold the counter to ,be attached for co-operation with the jacked shoe. It has been found that thecounter may be satisfactorily fastened to the sole of a turn shoe by useof four nails a, related as in Fig. 3 of the drawing. Here is shown theupper of a shoe S in place upon a last-L, and applied to it a counter C,to which is secured, by staples s, a shank piece P. Thecounter-attaching nails a pass through the shank-piece at opposite sidesof the longitudinal axis of the shoe and at points some.- what to therear of the breast-line of the heel, they being preferably arranged atthe corners of a rectangle. To bring these nails within the heel-seatarea and clear of the path of the attaching nails N for a wood heel H,such as is illustrated in Fig. 4, the

' position of the'counter-nails may be varied longitudinally of theshoe, three locations of the same design having been found generallysuflicientto establish the proper relations between the elements. Thecorresponding three sets of nail-receiving openings are indicated inFig. 1 at a, b and 0, respectively.

Carried upon the frame of the machine is a nail-distributing apparatus,including flexible nailtubes or conduits 18 mounted in a suitable holder20, which has a foot plate 22 in which the tubes terminate. In

opening 24, rec-- 26, the len th of which is such that a movement of thesection is permitted at least as great as the distance between the mostwidely separated sets of die-openings a and c. The plate-section may beguided in the opening by a rod 28 passing through a horizontal bore inthe section and entering openings 30, 30 in the foot-plate, this rodbeing held in place by a set-screw 82 threaded through the top of thesection. In the portion 26 is an opening 34 for each of the tubesl8,these corresponding in arrangement to each of the sets ofdie-openings a, Z) and c. Fulcrumed upon the footplate is a lever 36,connected to the section 26, conveniently by a slot through which theset-screw 32 passes. At the free end of the lever is an upturned end 38,serving as a finger-piece, and adjacent to this is an opening, which mayreceive any one of three pins 40 arranged upon the arc of a circle aboutthe fulcrum of the lever,-the adjacent pins being spaced from each otherto give settings of the plate-section, under the influence of the lever,to correspond to the three sets of die-openings. V To transfer the nailsfrom the distributing mechanism to the receiving-openings of the die andcounter-holding blocks, loading mechanism is provided, including an arm42 arranged to turn about the side-rod l2 and carrying the customaryloaderblock 44 with its movable nail-supporting shutter 45. In thisloader-block are sets of nail-receiving openings 46, corresponding tothose of the die-block and movable into alinement therewith. In theopposite eX- treme of movement of the loader-arm, when it is caught by alatch 48, the openings 46 he beneath some one of the positions of theopenings 34 of the foot-platesection, as determined by the engagementofthe adjusting lever with the pins 40.

Assume now that such a heel H is to be attached as is shown in fullylines in Fig. 4 of the drawing, with its attaching nails being locatedas appears at N. For this heel the nailing design for thecounter-attaching machine, furnished by the set a of die-block-openingsmay be correct. If the style of heel to be attached changes, as to thatappearing in dotted lines at h in Fig. 4, the inner pair of nails n ofthe previous nailing will be outside the breast-line of the heel, sothat their points will appear through the sole, in which case the lever36 may be shifted to the next pin 40, bringing the nail-delivering tubesinto position to supply the set Z) of receiving openings,

which will locate the nails or safely within the heel-seat area. Or suchan arrangement of heel-attaching nails may be desirable that thelocation of the set 0 of die-blockopenings may be the preferable one, inwhich case the adjustment of the foot-plate-section 26 to bring aboutthis delivery may be effected by the movement of its controlling leverto the third pin. 1Vhile three sets of openings have been described, itis obvious that, within limits, any other number might a receiving setsof fasbe employed, and that more or less than.
